AWNING.

SPECIFICATION forming part of Letters Patent No. 414,832, dated November 12, 1889.

Application-filed August 1,1889Iv .To all whom it may concern.-

Be it known that I, WILLIAM AsTRUP, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Awnings,'of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My invention relates to awningfframes and it consists of improvements hereinafter described and claimed.

Referring to the drawings, Figure l is a plan View of the frame. Fig. 2 is a front view of the same. Fig. 3 is a cross-sectional View taken through the frame A and the trusses. Fig. e is a detail central sectional View taken through the extremity of frame A and pipe B.

Heretofore in the construction of large business blocks in cities there have been used one or more central piers or supports for the front of the building, and as a consequence there have been suitable supports for awningframes at no great distance of separation from each other. Latterly', however, it has become t-he custom to support the front of the building on iron beams or girders without any central intermediate support. 'This has been for the purpose of increasing the size of the show-Windows, and an awning covering the front of such a building must necessarily have a very long stretch of frame, sometimes exceeding twenty feet in length. An awningframe of this length is very liable to be bent or forced inward by gusts of wind', and is also liable to become bent or sagged by reason of the long span and resultant heavy weight. My invention is designed to prevent this sagging and bending, and to form a strong, rigid, unyielding frame-work that will not shut off any light from the window, and yet will be of sufcient strength to withstand all needed pressure.

A is a longitudinal piece of gas-pipe provided with the threaded ends d, that are threaded int-o the elbow Z), the opposite extremities of said elbows having, respectively, threaded engagement with the side gas-pipe fralnes B. Into the adjoining extremities of both the longitudinal and side pipes or portions of the frame I insert, by driving, small sections of gas-pipe B ,in order to strengthen the extremities of gas-pipe at their points of juncture, where they are threaded into the elbows, and where they might otherwise be weak. It will of course be understood that the opposite extremities of said side portions are secured to the front of the building. A lateral truss C is secured to the longitudinal portion of the frame by means of the bolts c, that are tapped into the respective extremities of said longitudinal portion.m A second or depending truss D is secured iii like manner to saidlongitudinal frame. This depending truss prevents any downward sagging of the frame, while the lateral truss prevents anyinward yielding or bending of the frame.

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment of my invention. Change may be made therein, provided the principles of construction respectively recited in the following claim are employed.

I therefore particularly point out and distinctly claim as my invention- In an awning-frame made of gas-pipe, the combination of a longitudinal portion, two side portions, said longitudinal portion provided with a lateral truss and a depending truss, and strengthening-pieces inserted in said longitudinal and side portions at their points of juncture, substantially as set forth.

In testimony that I claim the foregoing to bemy invention I have hereunto set my hand this 30th day of July, A. D. 1889.
